Do you want to be the queen of your castle, a pirate captaining your own ship, or an explorer heading west? A trip to your local playground could be the perfect background for your next adventure. New playgrounds are popping up everywhere and are becoming more imaginative than ever. Have you ever wondered where the ideas for these cool playgrounds come from, or who is behind building your favorite park? We met up with Natalie Mackay, founder of Unlimited Play, to learn a little more about the design process of building playgrounds and how Unlimited Play is working with communities to make sure children of all abilities have the opportunity to play.
